Earthquakes

How do convergent plates move?

• They pull away from each other.

• They slide by each other.

• They move to connect to each other.

• It depends, sometimes they move close to each other, sometimes they move far apart.

What is the measure of the amount of ground shaking during an earthquake?

• Intensity

• Epicenter

• Magnitude

• Seismogram

Which scale rates earthquakes based on the amount of damage done?

• Mercalli Intensity Scale

• Richter Magnitude Scale

• Seismogram Shakey Scale

• Bernoulli Scale

Which seismic wave travels the fastest, always being the first detected by seismic stations?

• P waves

• S waves

• Surface waves

• Tsunami waves

The most destructive type of wave is a

• S-wave
• Surface wave
• transverse wave

How does the Richter Magnitude Scale calculate its measurements?

• Eyewitnesses

• Amount of damage caused

• The amount of time the earthquake lasted

• The strength of the seismic waves recorded by a seismograph machine.

What does a seismograph measure?

• The amount of oil and gas underground.

• The amount of damage an earthquake causes.

• The temperature of the earth's core.

• The amount of shaking of the crust.
